METHOD AND APPARATUS FOR EVALUATING RAILROAD TRACK STRUCTURE AND CAR PERFORMANCE

Method and apparatus for determining dynamic lateral and vertical wheel-rail forces. Axle bending sensors and axle load cells provide signals to a computer programmed to calculate lateral and vertical wheel-rail forces. These forces are used as the basis for comparing the effects of a variety of car...

Zusammenfassung:	Method and apparatus for determining dynamic lateral and vertical wheel-rail forces. Axle bending sensors and axle load cells provide signals to a computer programmed to calculate lateral and vertical wheel-rail forces. These forces are used as the basis for comparing the effects of a variety of car truck design criteria and track conditions. Comparison of forces developed by the same equipment on different runs over the same trackage discloses track condition changes between runs.
